Chapters

Specialist sub-communities inside Development Finance Nexus. Each chapter has its own group, editor and topic pages, and becomes a separate site only by meeting the graduation rule.

01In brief

The short answer.

Development Finance Nexus chapters are specialist sub-communities inside the platform: Infrastructure and Project Finance. Each has its own group, editor and research agenda starting from a cornerstone topic, and becomes a separate platform only by meeting the ten-point graduation rule.

02Canvas

From enquiry to contribution.

Canvas · from enquiry to contributionDesign, not a record
Chapters: a working group from charter to sunsetA charter sets the question and the code of conduct; members join with declared interests; a workplan produces deliverables that are reviewed and credited; the group reports and sunsets or renews. Design of the process, not a record of a run.

03Geography

People and exposure in Southern Africa.

For chapters, in GRA's spatial-finance reading, the map opens on night lights and population density with built-up and settlement extent from NASA GIBS, framed on Southern Africa; every other NASA layer, live feed and forecast waits in the layer list.

The interactive map needs JavaScript; the layer list and sources are below.

05Chapters

Development Finance Nexus chapters and their focus.

Chapters are specialist sub-communities inside Development Finance Nexus. Each has its own topic pages and follows the Development Finance Nexus boundary: no discussion of origination or arrangement of financing or safeguards categorisation of a project.

06Key terms

Terms used on this page.

Each term as this page uses it. Where a standard-setting body defines the term, the wording follows that body.

TermDefinition
ChapterIn the Nexus network, a specialist sub-community inside a platform with its own group, editor and research agenda; it can become its own platform only by meeting the published graduation rule.
Graduation ruleThe published ten-point test a chapter must meet, including sustained activity, editorial capacity, distinct scope, rights controls and operating ownership, before it becomes a separate platform.
Community of practiceA group of people who share a concern or a craft and learn to do it better by interacting regularly; the term comes from Lave and Wenger's work on situated learning.

09Questions

Questions and answers.

How does a chapter become its own platform?
Through the ten-point graduation rule: sustained activity, editorial capacity, distinct scope, rights controls, operating ownership and hosted acceptance, among others.
